Do not under any circumstances adjust this razor mid-shave with wet lather lubricated hands. In fact I never adjust this razor without a wash cloth over the head while I twist the handle with my other hand. I've learned this the hard way. That out of the way you'll really enjoy this kit as it gives terrific shaves. I think it's wise to start any adjustable you're unfamiliar with, at a low setting then as you refine your technique (and the Futur is somewhat different than other adjustables) gradually turn it up on subsequent shaves. You'll quickly find the sweet-spot that works best for you. This is a razor that's always in my weekly rotation. My only design complaint is the slippery handle which I address by having a hand-towel ready to keep one hand dry.
